It sounds good. It also sounds reasonable. It could very well be what Apple actually releases. The only thing that bothers me is some of the sources Mac Rumors cites. These include Mac OS Rumors and Kodawarisan.

My misgivings about the sources aside, Mac Rumors definitely has a talent for separating fact from fiction in these rumors. While there's still no way to know when we'll actually see these updates (although next week is still a possibility), we're getting an ever-more-clear picture of what they'll be.
